VEHICLE LOCK.

reissue fled October 16,

the invention is to provide a simple and efficient lock for vehicles of the type and particularly to provide a device for this purpose which operl ates by cutting as gasoline; and

oif the supply of fuel such with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying wherein 1 I Figure 1 is a view of a locking apparatus embodying the invention applied in the op erative position 2 is a J Figure 3 is a Fi dis a to a vehicle. plan view of the same-- sectional view thereof.

diagrammatic view showing the of the electromagnet to the valve j ta means. The device consists essent1ally of a spring a. closed fuel valve 10 which may be of any suitable H tuustra but which in the construction 1s provided with a normally actclosing spring 11 and which is arranged in the fuel feed line 12 between the reser- 9min or; tank 13 containing p the carbureter'14, with the usual form ordinary o w ith is, accessible to the fueland.

In the construction illustrated the stem is provided with a grip hand hold 16, and related with the stem Wis 'a. combination locking device 17 of any conventional type I turning of the stem serving to prevent. the to open the valve until 'theproper combination has been set through the adjustment of an index member 18 servljng to adjust the tumblers 19 in the lock easing. It will ific construction of the lock part of the present invention and forms no he understood that the mechanism t my uitable or conventional form of means serving ing of the valve stem may connection, mews should b to its to prevent theturnbe employed in but referabl the locking e suc that w on the valve valve closing position, the

a1 circuit 20 which includes 1925. Serial No. 62,944.

the ignition generator 21 of the vehicle is arranged an electro-magnet 22 and carried by the valve stem' is an armature 23 for attraction by the electro-magnet when the gen-V erator is in operation.

With this construction it is necessary that the motor be running and therefore that the generator be in action in order to energize the electro-magnet and attract the armature so asto hold the valve stem in a position tomaintain the fuel feed valve open. As soon as the motor stops and therefore the operation of the generator ceases the elec-tro-magnet becomes deenergized and releases the armature so that the valve closes and cuts oif In order to start the car it is necessary after setting the combination in order to release the valve stem, to hold the valve by means of the grip 16 in an open position until the motor starts and actuates the generator so as to produce a current suflicient to cause the electro-magnet to attract and hold thearmature and thus maintain the valve in an openposition. I The parts will then remain in running condition until the operation of the motor ceases whereupon the valve stem will be released as above indicated. I

Having described the invention, What is claimed as new and useful'is:

1. A vehicle lock having a fuel valve yieldingly held in its closed position, a combination lock mechanism for, normally preventing the opening movement of thevalve, and

means under the control of the generator of of an electro-magnet in circuit with the generator, and an armature carried by the valve magnet when tiom of e mobor vehiele, means shutting of? access f plant, a. lock for holding s 3.
